That's pure gloss. It isn't simply "changing your mind," it's changing the social and economic reality of 330,000,000 people. If you fuck up that messaging (science is absolute!) or fuck up plans (flatten the curve! -> eradicate covid! -> lol nvm its endemic now) you and all who support you deserve criticism.
Echoing my point on messaging, the director of the CDC says: “I have frequently said ‘we’re going to lead with the science’…I think public heard that as ‘science is foolproof. Science is black and white. Science is immediate and we get the answer and then we make the decision based on the answer'... and the truth is science is gray".
